Module Unix.IOVec

module IOVec: sig .. end

I/O-vectors for scatter/gather-operations

type 'buf t = private {

`buf :'buf;`	`(*`	Buffer holding the I/O-vector	`*)`
`pos :int;`	`(*`	Position of I/O-vector in buffer	`*)`
`len :int;`	`(*`	Length of I/O-vector in buffer	`*)`

}

Representation of I/O-vectors. NOTE: DO NOT CHANGE THE MEMORY LAYOUT OF THIS TYPE!!! All C-functions in our bindings that handle I/O-vectors depend on it.

val sexp_of_t : ('buf -> Sexplib.Sexp.t) -> 'buf t -> Sexplib.Sexp.t

val t_of_sexp : (Sexplib.Sexp.t -> 'buf) -> Sexplib.Sexp.t -> 'buf t

type 'buf kind

Kind of I/O-vector buffers

type bigstring = (char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t

val string_kind : string kind

val bigstring_kind : bigstring kind

val empty : 'buf kind -> 'buf t

empty the empty I/O-vector.

val of_string : ?pos:int -> ?len:int -> string -> string t

of_string ?pos ?len str
Raises Invalid_argument if designated substring out of bounds.
Returns an I/O-vector designated by position pos and length len in string str.

pos : default = 0

len : default = String.length str - pos

val of_bigstring : ?pos:int ->
       ?len:int ->
       bigstring -> bigstring t

of_bigstring ?pos ?len bstr
Raises Invalid_argument if designated substring out of bounds.
Returns an I/O-vector designated by position pos and length len in bigstring bstr.

pos : default = 0

len : default = String.length str - pos

val drop : 'buf t -> int -> 'buf t

drop iovec n drops n characters from iovec.
Raises Failure if n is greater than length of iovec.
Returns resulting I/O-vector.
